In this paper, novel small-signal averaged models for dc-dc converters operating at variable
switching frequency are derived. This is achieved by separately considering the on-time and …

For electric vehicles, the improvement of the range of miles and with it the utilization of the
available cell/battery capacity has become an important research focus in the community. For …

The importance of online system identification (SI) in power electronics is ever increasing. It
enables the tracking of system parameters, which in turn can be used for online controller …

Due to the steadily-increasing demands on more powerful electronic devices, an accumulator's
operating lifetime plays an essential role for the usability of battery-powered devices. To …

A reliable knowledge of cell parameters like the state-of-charge (SoC) is essential for the
optimization of battery-powered applications. Usually, during relaxation (the phase of no or low …

Online system identification provides the possibility to track system changes and thus is the
basis for successive adaption of control parameters. This paper introduces a concept for fast, …

The tracking of the internal states of a battery such as the state-of-charge (SoC) is a substantive
task in battery management systems. In general, batteries are represented as linear or …

Optimizing the battery management of today’s portable electronic applications goes hand in
hand with the reliable and accurate knowledge of the battery’s state-of-charge (SoC). During …

Recently, we proposed approximate least squares (ALS), a low complexity approach to
solve the linear least squares problem. In this work we present the step-adaptive linear least …

Portable battery-powered applications are heavily affected by the growing variety of provided
functionalities. As the applications get more and more powerful, optimization of power-…
